Problems solved by technology

[0003] And the gel fire extinguishing material that adopts in the prior art is that the finished gel has shelf life, is not easy to store for a long time, and coal mine spontaneous fire possesses suddenness, can't adjust the use of gel according to different fire intensity, makes its practicability poor, and present Gel fire extinguishing material is easy to fall off from the substrate after high temperature heating, reducing the fire extinguishing effect

preparation example Construction

[0023] The gel material is prepared by mixing the coagulant with 5-15% of water and then mixing with the mixture of water glass compound, flocculant and remaining water. Before the preparation of fire extinguishing, the water glass compound and the coagulant cannot be in contact with each other to prevent the reaction between the two, and then the reticulated colloidal silicic acid obtained by the reaction of the two will become invalid during storage.

[0024] In the process of using the gel material to extinguish the fire, the coagulant and part of the water are mixed to obtain the first mixture, while the water glass compound, the flocculant and the remaining water are mixed to obtain the second mixture, which are stored in different mixing tank cars , can be operated at any time. When a fire breaks out, mixing the first mixture and the second mixture can quickly produce colloid, and then spray the colloid to the fire place, and then the colloid adheres to the surface of th...

Embodiment 1

[0032] This embodiment provides a kind of gel fire extinguishing material, and the gel fire extinguishing material comprises water glass accounting for 13% of the mass of the gel fire extinguishing material, sodium bicarbonate accounting for 3% of the mass of the gel fire extinguishing material, sodium bicarbonate accounting for 2% of the mass of the gel fire extinguishing material polyferric sulfate, and the rest is water.

[0033] This embodiment also provides a preparation method of the gel fire extinguishing material: mixing sodium bicarbonate and 5% water and then mixing with water glass, polyferric sulfate and the remaining water.

[0034] The method of use is: stir and mix 3% sodium bicarbonate and 5% water to obtain the first mixture, 13% water glass, 2% polyferric sulfate and the remaining water to stir and mix the second mixture, and then mix the first mixture Mix with second mixture and transport to ignition point.

[0035] This embodiment also provides a fire exti...

Embodiment 2

[0038] This embodiment provides a kind of gel fire extinguishing material, and the gel fire extinguishing material comprises water glass accounting for 20% of the mass of the gel fire extinguishing material, sodium bicarbonate accounting for 15% of the mass of the gel fire extinguishing material, sodium bicarbonate accounting for 3% of the mass of the gel fire extinguishing material polyferric sulfate, and the rest is water.

[0039]This embodiment also provides a preparation method of the gel fire extinguishing material: mixing sodium bicarbonate and 10% water and then mixing with water glass, polyferric sulfate and the remaining water.

Abstract

The invention relates to the field of fire extinguishing materials, in particular to a gel fire extinguishing material, a fire extinguishing material and a blocking agent. The gel fire extinguishing material is prepared from a water glass compound which accounts for 13-20% of the mass of the gel fire extinguishing material, a coagulant which accounts for 3-15% of the mass of the gel fire extinguishing material, a flocculant which accounts for 2-3% of the mass of the gel fire extinguishing material, and the balance of a blending agent. The fire extinguishing material can be stably spliced on basal bodies such as a coal mine, is difficult to fall off and fracture, and generates no harmful gas in the process of fire extinguishing.

Description

technical field [0001] The invention relates to the field of fire extinguishing materials, and in particular to a gel fire extinguishing material, a fire extinguishing material and a blocking agent. Background technique [0002] As the scope of goafs in coal mines continues to increase, mine pressure is becoming more and more obvious. Coal pillars and airtight pressure in goafs are easy to form cracks, and air leakage in goafs increases, which is very easy to cause spontaneous combustion of floating coal in goafs. Once a fire breaks out underground, the method of directly using water to extinguish the fire is usually adopted. However, when water passes through hot coal above 600°C, water gas will be generated, and it is very easy to induce water gas explosion, causing secondary accidents; and the existing yellow mud grouting system cannot meet the requirements of small areas. , Sudden fire, and poor mobility; Nitrogen injection for fire extinguishing Because nitrogen is easy...
